DeLaval ID reader walk by IRW Planning Planning DeLaval ID reader walk by IRW 1 General 233226 General points to consider before ordering and installing the IRW: Fig. 1 n DeLaval ID reader walk by IRW is used to identify cows with B-transponders or ISO transponders. n The IRW will be set to read either B or ISO transponders, meaning that the entire herd must have the same type of transponder. n ISO transponders must be attached to the same ear for the entire herd.

DeLaval ID reader walk by IRW Planning 4 Reading range 217250 The reading range is the area in which the IRW can read a transponder. An electromagnetic field is used to read the transponders. Fig. 3: Electromagnetic field from the IRW. To get a good reading range, a "safety area" must be used around the IRW. Inside this area it is not allowed to have metal-reinforced building structures or other metal equipment that might short circuit the electromagnetic field of the IRW.
DeLaval ID reader walk by IRW Planning 5 Placing the IRW at a parlour or rotary entrance Note! It is important to plan the entrance correctly so that only one cow at a time is picked up by the IRW. n The IRW should be located directly in front of, or as close as possible to, the parlour entrance gate. n Separate the return cow traffic from the single cow walkway close to the IRW so that no unwanted transponders are read by the IRW. – A regular steel fence is recommended.
DeLaval ID reader walk by IRW Installation Installation DeLaval ID reader walk by IRW 1 General Warning! The equipment is heavy and could cause serious crushing injury if dropped. Note! It is recommended to have two fitters available when lifting and installing the IRW. Note! Working transponders are needed. Note! Take care when installing the IRW. Incorrect installation will result in poor system performance with unacceptable levels of missed identification.

DeLaval ID reader walk by IRW Installation 3 Installing the photocell To install the photocell: 1. Determine which slot the photocell should be installed in. In general the photocell should be installed in the slot closest to the parlour. If the entrance gate is close to the antenna and if there is a possibility for the cows head to be outside the reading range, the photocell should be install in the first slot. 233232 Note! Only for HB30/50. Fig. 10: Photocell installation slot. © DeLaval 2015.
